Construction and function

General description
The electronic high performance power supplies of the PSI 10000 3U series are especially suitable for industrial test which
have a demand for high power. There are models with a rated power of up to 15 kW, offering high currents or high voltages
to cover a broad spectrum of applications.
Apart from basic functions of power supplies, set point curves can be generated in the integrated function generator (sine,
rectangular, triangular and other curve types). Arbitrary generator curves can be saved to and loaded from an USB stick.
For remote control the devices are provided as standard with USB and Ethernet ports on the rear side, as well as a galvanically
isolated analog interface. Via optional plug-in interface modules, other digital interfaces such as for RS232, Profibus, ProfiNet,
ModBus TCP, CAN, CANopen or EtherCAT can be added. These enable the devices to be connected to standard industrial
buses simply by changing or adding a small module. The configuration, if necessary at all, is simple.
In addition, the devices offer as standard the possibility for parallel connection in so-called Share bus operation for constant
current sharing, plus a true master-slave connection with totaling of all actual values is also provided as standard. Operating
in this way allows for up to 64 units to be combined to a single system with a total power of up to 960 kW.
